AUTOMATIC DANI PER-REGULATO R.

SPECIFICATION forming part of Letters Patent No.`607,900, dated July 26, 1898. Application filed March 5, 1896. Renewed .Tune 9,1898. Serial No. 683,037. (No model.)

To @ZZ wle/0771, it may concern:

' Be itknown that I, CHARLES F. WOOD, a citizen of the United States, residing at Wayne, in the county of Delaware, State of Pennsyl` Vania, have invented a new and useful Improvement in Automatic Damper-Regulators,

tures of which will be hereinafter set forth,

and specifically pointed out in the claims.-

Figure l represents a side elevation of. a portion of a direct indirect steam-heating system embodying my invention, the casing and walls of the apartment being shown in sections. Eig. 2 represents a side elevation of a portion of a direct indirect steam-heating system, the casing and floor being shown in sections. Scale, a side elevation of a portion of a direct indirect steam-heating system, showing the manner of piping and connecting the radiator and its adjuncts. Fig. 4. represents, on an enlarged scale, a perspective view of the base or casing employed, the latter being shown in detached position. Fig. 5 represents a side elevation of a portion of a direct indirect steam-heating system, the lower portion of the same being shown in section.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the lower portion of a radiator employed in a direct indirect steam-heating system, and B a base or casing partly inclosing the lower portion of the same, said casing consisting of the upright sides C, one of which has an opening D leading into the apartment in which the radiator is located, while from the other side the passage E extendsthrough the walls of the apartment into the exterior air, the grating F being located at the terminal of said passage E, if desired, as seen in Fig. l. G designates a damper employed, which` is pivoted at the point I-I below the radiator A, the casing B being provided with an upright partition H', located below said pivot-al point. J designates a weight or counterbalance attached to said damper G, the movement of the latter being limited in either di- Fig. 3 represents, on a reduced as shownV in Fig. l.

rection by means of the ledgesA K and L, attached to either side of the sides C.

M designates a plunger or rod attached to the diaphragm P of the damper-regulator N,

`the construction of the same being evident from the sectional view in Fig. 5.

y Q designates a pipe leading from the top of said damper-regulator to the interior of the radiator A, as will be lunderstood from Figs. l, 2, and 5, whereby it will be seen that any variations of the steam-pressure within the radiator will actuate the plunger M, thereby imparting the desired extent of movement Ato the damper G, the plunger contacting with the same at one side of'its pivotal point.

In Fig. 2 is shown a construction similar to Fig. l, the lateral passage E, however, being replaced by the upright passage E, as may be expedient under some conditions, the damper G being pivoted at the point H2 and provided with the counterbalance J, as before, while the extent of movement ofsaid damper is limited by ledgesK and L', the relative arrangement and location of the same being evident from Fig. 2.

In Fig. 3 I have shown another embodiment of the principle of my invention, the connection to the regulator N being made from the radiator A through the medium of the pipe N2, the action of the plunger M upon the damper G being the same as above described, the device shown in Fig. 3 being applicable to direct indirect steam-heating systems.

The operation is as follows: Reference being first had to Figs.,1, 2, 4:, and 5, it will be apparent that the damper G is to be carefully balanced and so arranged as to close the opentimes except when the pressure of steam in the radiator, is so great as to operate the damper so as'toentirely open the passage E, Thepartition H (seen in'Fig. l) prevents the air from passing directly from the outside to the interior of the apartment lat such times as the damper occupies the middle position between the two openings.

IOO

The diaphragm P, which is used in the damper, is of special construction, carefully adjusted, and is connected directly with the radiator, either inside or outside of the base, as may be desired, or with the piping which supplies the radiator with steam, and is so connected With the plunger M that when actuated by an excess of pressure of steam in the radiator it depresses the adjacent end of the damper with Which it is in contact, so as to open the passage E, and thus admit of the entrance of the cold air Without to the base of the radiator.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A radiator having a casing or conduit located adjacent thereto and opening into an apartment, a passage leading from the exterior airinto said conduit, a daniperlocated in said conduit and adapted to control said opening and said passage, a chamber having a diaphragm therein, and in communication With the interior of said radiator, a plunger attached to said diaphragm, and adapted to actuate said damper, and stops to limit the movement of the latter.

2. In combination with a radiator, a casing or base located adjacent the lower portion of the latter, a conduit leading thereto from the exterior air, and an opening into said casing from the apartment in which the radiator is located, a counterbalanced damper pivotally mounted in said casing and adapted to control said conduit and said opening, an upright partition in the latter extending from the pivotal point of said damper to the base of said casing, means 'for limiting the movement of the damper, a regulator mounted adjacent t-he latter and provided With a plunger having one end adapted to actuate said damper, the other end of said plunger being connected With the diaphragm connected With the radiator, and connections intermediate the regulator and radiator.

3. The combination of a radiator, with a base or casing, an opening in one side of said casing to admit air from the apartment in which the radiator is located, a passage leading from the exterior into said casing, a balanced damper within said casing intermediate said passage and opening and adapted to control the ingress ot' the exterior air, and means for automatically operating the same by the variations of pressure of the heating medium in the radiator or its connections.
